BACKGROUND OF INVENTION

1. Field of Invention

The present invention relates to a cup and, more particularly, to a lid assembly for a cup.

2. Related Prior Art

Lids can be used to keep beverage in cups. Such a lid can be attached to such a cup by fitting or engagement of threads.

As disclosed in Taiwanese Patents M420265, M458384, M4591991 or M460845 for example, a coffee cup can be used with a lid that is made with an exit and formed with or connected to a cover for covering the exit.

Such a coffee cup is often used to contain coffee. A user lifts the cover from the lid and then drinks the coffee from the coffee cup via the exit of the lid. It takes a very short period of time for the coffee to reach the user's mouth from the coffee cup. It is difficult to cool the coffee to a comfortable temperature for the user to drink in such a short period of time. The user might get burnt by the coffee.

Therefore, the present invention is intended to obviate or at least alleviate the problems encountered in prior art.
